Diagnosis
Small, cup-shaped lorica with two collars. Inner collar superimposed on outer one. Oral rim always devoid of teeth.
Arranged in Subgroup 4C (see the page Ti. 15 Classification scheme based on morphologically similar groups of species).
Species treated (marked with * are dubious species):
*Ascampbelliella acuta (Kofoid and Campbell, 1929)
*Ascampbelliella armilla (Kofoid and Campbell, 1929)
Ascampbelliella obscura (Brandt, 1906)
Ascampbelliella urceolata (Ostenfeld, 1899)
All records of Ascampbelliella species are based on only a few specimens, so morphological descriptions are still scarce and incomplete.
